A kind of dry-type air-core reactor

Technical field

The utility model relates to a kind of dry-type air-core reactor.

Background technology

In the electric traction system, the application of dry-type air-core reactor is very extensive.The coil of existing dry-type air-core reactor is to be formed by the tight coiling of copper strips, insulate with insulation film between the copper strips of coil, coil is fixed on the insulating mounting plate of reactor both sides by 4 screw rods, on the insulating mounting plate angle steel is housed, reactor is lifted under the car by angle steel, the dry-type air-core reactor Heavy Weight of this structure, amount of copper consuming is big, the cost height, overload capacity is poor, is not suitable for the situation of big electric current, big inductance, many windings on the strength structure; And existing dry-type air-core reactor is installed under the car body, when vehicle travels out of doors in the rain, the inner easily water inlet of dry-type air-core reactor, and waterproof measure is not taked in line and lead-out wire and winding coupling part between winding, adaptability to adverse circumstances is not strong, very easily cause electric fault, make coil turn-to-turn short circuit; Especially insulating barrier easily produces offset phenomena in the bad working environments lower coil of impact shock, can cause the dry-type air-core reactor winding deformation when serious; The maintenance trouble, useful life is short.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of in light weight, and overload capacity is strong, stable performance, and adaptive capacity to environment is strong, has water-proof function, long service life, dry-type air-core reactor easy to maintenance.

The technical solution of the utility model is: it comprises at least one group of reactance unit, shell, the abnormity insulating barrier, draw bus, terminal box, described shell is a modular construction, shell comprises that two are installed side plate, following ventilating board, preceding ventilating board and rear venting plate, described reactance unit is made up of two above square coils, square coil is surrounded by compound inslation band and glass fiber tape outward, the outside of adjacent square molded lines circle is provided with cleat insulator with side plate is installed, each is organized between the reactance unit and has been equipped with four special-shaped insulating barriers separating supporting role between each square molded lines circle, be beneficial to form insulation and form heat dissipation wind channel, each special-shaped insulating barrier both ends clamps by bolt, the fishbolt of its outer end fastens as one with the installation side plate respectively, the reactance unit end is provided with brace, drawing bus one end is connected with brace, the other end is fixed on the mounting panel of terminal box, before being located at, terminal box on the ventilating board, the WATERPROOF PACKING GLAND of inlet wire cable is housed on the terminal box box wall.

There is projection described special-shaped insulating barrier both sides, are beneficial to make square coil reliably to locate.

Described terminal box should adopt split type structure, is beneficial to carry out the wiring operation in small space, is convenient to maintenance.

Described square coil is made by the aluminium magnet strip coiling that scribbles coatings and through the high thermal endurance class insulating varnish of vacuum impregnation, is beneficial to improve insulation property, improves water resistance, is compared by copper strips coiling winding with existing, helps weight reduction, reduces cost.

Connection between described square coil winding is adopted and is welded to connect.

Connection between described reactance unit is adopted and is welded to connect.

Connecting portion between the described square coil and draw the busbar joint place and adopt waterproof insulation glue and silicon rubber self-adhesive tape, glass fiber tape to seal is to guarantee the reliability of excellent waterproofness and insulation.

The utility model can be determined the quantity of whole reactor winding according to different inductance values and electric current, takes different connections and outlet method to satisfy the special requirement of different automobile types electric traction system; Be equipped with special-shaped insulating barrier between each square coil and each reactance unit, be beneficial to form insulation and form heat dissipation wind channel, reduced temperature rise; The special-shaped insulating barrier of each layer both ends clamp by bolt, the fishbolt of its outer end is respectively at fastening as one with two installation side plates, can effectively guarantee to guarantee the needs of its product overall construction intensity under vibration environment reliable to the situation of the multi-thread circle of the big inductance of big electric current.

Product of the present utility model has that dielectric strength height, loss are little, noiseless, anti-aging, corrosion-resistant, have water-proof function, reliable characteristics, can long-time running under various mal-conditions.
